The PremAire Cadet Respirator is a pressure-demand device, meaning it delivers respirable air to the user on demand. As such, it maintains a slight positive pressure of air inside the facepiece -- whether the wearer is inhaling or exhaling -- to prevent contaminants from entering the facepiece, should any slight face-to-facepiece seal leakage occur. Because the unit is a pressure-demand device, it can be used with a large, compressed air cylinder or a bank of cylinders set up in cascade fashion. For longer-duration air supplies, the respirator also can be used with a compresor that delivers respirable air to the user within the NIOSH-approved pressure range.

Features: Economical combination supplied air respirator with excape cylinder in a streamlined, lighweight design. Escape cylinders rated at 5, 10 and 15 minutes. Streamlined new design offers a first-stage regulator and cylinder valve within one assembly, creating a very small size and profile that is less likely to snag when working in tight places. Cylinders can be worn on left or right hip. Ultra Elite Pressure-Demand Facepiece or Advantage 4000 Facepiece with APR conversion capability offer choice of sizes and nose cups. Cost-effective respiratory protection solution for many industries
